Abstract

PROCEDURE FOR OBTAINING A COPOLYMER OF ALPHA-METHYLLESTIRENE AND ACRYLONITRILE IN AQUEOUS DISPERSION, IN THE PRESENCE OF A COMPOUND THAT SUPPLIES FREE RADICALS. IT CONSISTS IN THE REACTION OF POLYMERIZATION OF A WATER DISPERSION OF ALPHA-METHYL-STYRENE AND ACRYLONITRILE, CONTROLLING THAT THE TEMPERATURE OF THE DISPERSION DOES NOT EXCEED 110 DEGREES DEGREE AND THE AVERAGE SPEED OF ELEVATION OF THE TEMPERATURE IS A LESS THAN 60 DEGREES DEGREE PER HOUR. THESE COMPOUNDS HAVE APPLICATIONS FOR THE MANUFACTURE OF HOUSEHOLD AND ELECTRICAL ITEMS AND AUTOMOBILE PARTS, AS WELL AS TO IMPROVE THE HEAT RESISTANCE OF OTHER SYNTHETICS.
